Guyana is the third poorest country in Latin America and the Caribbean, but it could soon become one of the top oil producers in the region.

That’s because of a huge, recent discovery of oil in the waters off its coast, which U.S. oil giant Exxon Mobil – lead explorers in the search – are calling a “significant” find.

The small former British colony with a population of less than one million has no previous oil industry. So correspondent Stephen Gibbs traveled there to investigate how striking oil may change Guyana for better or for worse.
